最近提出的互易关系指出，从结到电池端子的电流传输效率可以通过区分发光图像相对于端子电压来确定。本文通过与同时测量的电流和模拟进行比较，实验表明了这种关系的有效性。此外，我们验证了该方法是适用于各种光浓度和施加的电压，这使我们能够调查在相关条件下的细胞。结果表明，影响电流传输效率的几种串联电阻。我们表明，这些不同的电阻的相对贡献的损失在电流收集是一个函数的照明强度。
A recently suggested reciprocity relation states that the current transport efficiency from the junction to the cell terminal can be determined by differentiating luminescence images with respect to the terminal voltage. The validity of this relation is shown experimentally in this paper, by comparison with simultaneously measured electrical currents and simulations. Moreover, we verify that the method is applicable under various light concentrations and applied voltages, which allows us to investigate the cell in relevant conditions. Results evidence several kinds of series resistances affecting the current transport efficiencies. We show that the relative contribution of those different resistances to the loss in current collection is a function of the illumination intensity.
